I believe I read somewhere that if you don’t have a word for a color, it’s harder for you to conceptualize of it. For instance, if you have just the word “blue”, it’s harder to distinguish between light blue and dark blue than if you have two separate words in your language for blue. Or by having the words “fuchsia” and “salmon”, you can pick them out of the vast sea of “pink”, whereas it’s harder to do that if it’s all just “pink” to you.
